Motor propelled toy vehicle



Feb E59 i949. A. ADAMQZYK MOTOR PROPELLED TOY VEHICLE Filed Dec. 11,194e Patented Feb. 155,` 1949 sna'haft"extending transversely to theaxis of the Wheels are known. However, such a wheel is incapable oflifting the front part of the vehicle above the level of the travelsurface, nor cause the toy to turn when traveling on. an even surface orreaching a wall.

With these and other objects in view that will be apparent from thedetailed description of my invention, the latter consists in the novelconstruction, combination and arrangement of parts as will behereinafter specified and defined in the appended claims. y

In the accompanying drawing which constitutes part of this specificationand in which similar reference characters denote corresponding parts:

Fig. 1 is a side elevation of my toy vehicle,

Fig. 2 is a top plan view thereof,

Fig 3 is a side elevation of a modified construction,

Fig. 4 is a cross section on line 4-4 of Fig. 2, and

I denotes the chassis of the toy vehicle pro vided with front wheels II,I2, mounted on a shaft I3 and rear Wheels I4, Wheel, say I4, is idle,being fixed on a sleeve rotatively mounted on the motor driven shaft I6and the other wheel I5 is xed to said shaft. Extending longitudinally ofthe chassis and at a right angle to the shafts I3, I 6, is a shaft I1,slideably and rotatively mounted in bearings I 8. I9 denotes a wheel,disc or like member, which is shaped as shown in Fig. 4, and fixed onshaft I1 and projects downwardly through a recess provide I *f#2,451,642, A

I5, of Iwhich one lowered, as shown in Fig. l, as a result of which themember I9 comes to bear on said travel sur face. Due to friction exertedbetween said mem-A ber and said surface, movement of the vehicle in thesame direction will cease, while due to inertia and against the tensionof its spring I8a said member will be pushed rearwardly, causing thegear 2| to engage the motor driven gear 22 and at the same time the gear23 to engage the gear 24 of the idle wheel I4. This has the effect thatthe member I9 will be set into rotation and due to its shape or itseccentric mounting, will lift the front part of the vehicle above thelevel of the travel surface T, and at the same time change the course-ofthe vehicle. This change of direction of travel is facilitated by therotation of the idle Wheel I4 in the direction opposite to that of thedriven wheel I5, which rotation is imparted to it by the engagement ofgear 23 with f gear 24.

In the modification shown in Fig. 3, means are provided whereby thevehicle automatically may be caused to change its direction of travelintermittently.`

In the present example, these means comprise a rotary Wheel, disc ormember 26 which is suitably impelled by the motor. This member 26 haspivoted to it eccentrically as at 21a a rod 21 extending forwardly andlongitudinally of the chassis. The front end of said rod 21 is providedwith suitable means, such as a hook shaped part 21h capable of engagingthe member I9, so that, during the rotation of the member 26, said rodwill reciprocate and intermittently pull the lively supported on saidframe member I9 rearwardly, as a result of which the vehicle will becaused to change its direction of travel, as already explained.

In the constructions heretofore described, wheel I9 is provided withmeans by which it will be moved rearwardly so that its shaft l1-wil1 becoupled to the motor 22a' Such coupling, how,- ever, may be dispensedwith. In such case, the locking action of wheel i9 will cause the drivenrear wheel to swing the toy around the idle wheel, and after the wheeli9 has made one turn and the front part of the toy is turned back to thetravel surface, spring I8a will bring Wheel I9 in contact with thelocking stop I8@l thus permitting the toy to travel in the newdirection.

' travel.

Each change of the course of `travel may be signalled either visually orby sound. To this end, I provide a suitable device 28, using an electricbulb 30, bell or the like. The electricY circuit actuating said device`may be controlled by a switch 29 to be operated by the forward end Ha ofthe shaft Il, so that every time the shaft il is moved rearwardly itwill'close or open the electric circuit. v

While I have described my toy in connection with a vehicle, it isobvious that the construction may be modied in various ways withoutdeparting from the principle of my invention, so as to be alsoapplicable to vfigures simulating humansV or animals. I, therefore, donot wish to restrict myself to any details of construction described andshown herein.

What I claim is:

1. In a self propelled toy, having a motor and frame with a pair of rearand front Wheels in which at least one of the rear wheels is motordriven and the other rear wheel idle, a spring inuenced eccentric memberslideably and rotatintermediate its ends, and adapted normally tobe outof contact withthe travel surface, but to contact the latter 2. A motorpropelled toy, according to claim 1, in v,which motor drivenv'"reciprocatory means are provided which are adapted to intermittentlypull said eccentric member rearwardly into operating connection with themotor so as to cause the vehicle to intermittently change its course.

3. A motor propelled toy, according to claim 1, in which are provided amotor rotated element, a

l rod eccentrically pivoted at one end to said element and extendingforwardly from said element,

and means on the opposite end thereof capable of engaging said eccentricmember and, when reciprcated by the rotation of said' element, tointermittently pull said member rearwardly into operative engagementlwith said motor4 and thereby automatically cause the toy tointermittently change its course of travel.
